Objective:To explore the effects of embodied emotion priming on attentional bias of individuals with depression tendency.Methods:From June to December 2018, a total of 91 college students with depression tendency were recruited to participate in the experiment.A 3(embodied emotion priming: positive priming, negative priming and no priming) × 2 (emotional face: happy and sad) mixed design was adopted to measure the attentional bias of individuals with depression tendency using the dot probe paradigm. SPSS 22.0 statistical software was used for repeated measurement analysis of variance.Results:In terms of attentional bias, the interaction effect between embodied emotion priming types and emotional faces was significant ( F(2, 88)=5.97, P=0.004, ηp2=0.119). Further simple effect analysis showed that, under the happy-face condition, participants' attentional bias reaction time(△RT) was significantly higher when primed with embodied positive emotion than those primed with embodied negative emotion((14.30±18.23)ms, (-6.53±38.17)ms, P<0.05). The participants' attentional bias △RT was significantly lower when primed with embodied negative emotion than participants with no priming ((-6.53±38.17)ms, (9.16±30.62)ms, P<0.05). Under the sad-face condition, the participants' attentional bias △RT was significantly higher when primed with embodied negative emotion((28.22±35.33)ms) than participants primed with embodied positive emotion((11.71±29.24)ms, P<0.05) and no priming ((7.63±30.60)ms, P<0.05). Conclusion:Embodied emotion priming can affect the attentional bias of individuals with depression tendency.

Bicyclol is a synthetic drug for hepatoprotection in clinic since 2004. Preliminary clinical observations suggest that bicyclol might be active against hepatitis C virus (HCV) with unknown mechanism. Here, we showed that bicyclol significantly inhibited HCV replication and in hepatitis C patients. Using bicyclol as a probe, we identified glycolipid transfer protein (GLTP) to be a novel restrictive factor for HCV replication. The GLTP preferentially bound host vesicle-associated membrane protein-associated protein-A (VAP-A) in competition with the HCV NS5A, causing an interruption of the complex formation between VAP-A and HCV NS5A. As the formation of VAP-A/NS5A complex is essential for viral RNA replication, up-regulation of GLTP by bicyclol reduced the level of VAP-A/NS5A complex and thus inhibited HCV replication. Bicyclol also exhibited an inhibition on HCV variants resistant to direct-acting antiviral agents (DAAs) with an efficacy identical to that on wild type HCV. In combination with bicyclol, DAAs inhibited HCV replication in a synergistic fashion. GLTP appears to be a newly discovered host restrictive factor for HCV replication, Up-regulation of GLTP causes spontaneous restriction of HCV replication.

Objective To investigate the diagnostic value of intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)in differentiating non-metastatic from metastatic mesorectal lymph nodes in rectal cancer.Methods IVIM-DWI and DCE-MRI were performed preoperatively in 38 patients with histologically proven rectal carcinoma.The short axis diameter,short-to-long axis diameter ratio,four IVIM-based parameters (ADC,D,D? and f) and six DEC-MRI semi-quantitative parameters (Slope,Maxslope,CER,Washout,TTP,iAUC90 and iAUC180 )were compared between the metastatic (n=28)and non-metastatic (n=27)lymph nodes.Results There were significant statistical significances between the metastatic and non-metastatic lymph nodes in mean short axis diameter (8.87 mm±2.829 mm vs 6.83 mm±1.075 mm),D value[(0.824±0.1 13)× 10 -3 mm2/s vs (1.033±0.244)× 10 -3 mm2/s],CER(1.588 ±0.664 vs 1.054 ±0.41 9),iAUC90 (22.89 ± 9.83 vs 13.59 ± 5.34)and iAUC1 80 (49.38±20.1 9 vs 30.31 ± 1 1.67)(P ≤0.001).The short-to-long axis diameter ratio,ADC,D? ,f,Slope,Maxslope,Washout and TTP values did not show significant differences between the two groups(P >0.05).The respectively optimal cut-off value (area under the curve,sensitivity and specificity)for distinguishing metastatic from non-metastatic lymph nodes were as follows:short axis diameter=7.1 mm(0.744,64.2%,85.1%),D=0.906×10 -3 mm2/s (0.821,81.5%,75.0%),CER=1.05(0.749,85.7%,62.9%), iAUC90 =13.42(0.780,85.7%,62.9%),iAUC180 =49.65 (0.770, 50.0%,100%)respecyively.Conclusion Both IVIM-DWI and DCE-MRI are useful for differentiating non-metastatic from metastatic mesorectal lymph nodes in rectal cancer.

Lignin degradation products are toxic to microorganisms, which is one of the bottlenecks for fuel ethanol production. We studied the effects of phenolic ketones (4-hydroxyacetophenone, 4-hydroxy-3-methoxy-acetophenone and 4-hydroxy-3,5-dimethoxy-acetophenone) derived from lignin degradation on ethanol fermentation of xylose and cellular lipid composition of Pichia stipitis NLP31. Ethanol and the cellular fatty acid of yeast were analyzed by high performance liquid chromatography (HPLC) and gas chromatography/mass spectrometry (GC/MS). Results indicate that phenolic ketones negatively affected ethanol fermentation of yeast and the lower molecular weight phenolic ketone compound was more toxic. When the concentration of 4-hydroxyacetophenone was 1.5 g/L, at fermentation of 24 h, the xylose utilization ratio, ethanol yield and ethanol concentration decreased by 42.47%, 5.30% and 9.76 g/L, respectively, compared to the control. When phenolic ketones were in the medium, the ratio of unsaturated fatty acids to saturated fatty acids (UFA/SFA) of yeast cells was improved. When 1.5 g/L of three aforementioned phenolic ketones was added to the fermentation medium, the UFA/SFA ratio of yeast cells increased to 3.03, 3.06 and 3.61, respectively, compared to 2.58 of the control, which increased cell membrane fluidity and instability. Therefore, phenolic ketones can reduce the yeast growth, increase the UFA/SFA ratio of yeast and lower ethanol productivity. Effectively reduce or remove the content of lignin degradation products is the key to improve lignocellulose biorefinery.

Objective To explore the outcomes of the transplanted kidney as donor for clinical renal transplantation and summarize experience in combination with related literature.Method This study retrospectively analyzed the clinical documents of one case of uremia receiving renal allograft transplantation with the transplanted kidney as the donor in one case of renal transplantation after brain death in February,2015.The donor was a 31-year-old man who received renal transplantation for uremia in November,2014 and obtained normal renal function.Two months later,the patient was brain dead because of neurologic disorder and donated his transplanted kidney.The serum creatinine of the donor was 167 μmol/L,and the glomerular filtration rate was about 35 mL/min befor donation.The recipient was 27 years old who needed transplantation because of chronic renal function failure and uremia.Preoperation tests showed that PRA was negative,and serum creatinine was 1 353 μmol/L.After separating and dissecting the donor kidney carefully,we perfused and compensated the kidney by Lifeport Organ Perfusion and Preservation Conveyor.The warm ischemia time was about 15 min.The renal vein of the donor was anastomized with right external iliac vein of the receptor,artery with right external iliac artery,and ureter with right centrifugal ureter.Result The operating time was more than 3 h.Postoperatively,the recipient was given the immunosuppressive regimen as tacrolimus,mycophenolate mofetil and methylprednisolone to prevent rejection.At 1 st day postoperation,the 24-h urine volume of the receptor was 5 000 mL,serum creatinine was declined gradually to a minimum of 180μmol/L,and there was trace urine protein.The renal function of patient recovered well by now.Meanwhile,the patient was still under the follow-up.Conclusion It is practical that using transplanted kidney as donor kidney for re-transplantation.There were certain clinical significance for shortening the waiting time of renal transplantation in uremia patients and relieving the shortage of transplant kidney.

Objective To investigate clinical presentations,laboratory examinations,magnetic resonance imaging (MRI) appearances and treatment of hypertrophic cranial pachymeningitis (HCP).Methods The clinical data of 13 patients with HCP receiving comprehensive therapy in Huashan Hospital from January 2007 to January 2013 were analyzed retrospectively.Results The onset of HCP was mostly chronic with an average duration of 26.7 months.The main clinical manifestations of the 13 patients were chronic headaches (12/13) and cranial nerve paralysis (12/13).Inflammation markers and cerebro-spinal fluid (CSF) protein levels increased in patients with HCP and gradually became normal after the treatment.The MRI demonstrated local or diffused thickened dura located in tentorium (10/13),falx cerebrum (5/13),frontal lobe (4/13),temporal lobe (7/13) and parietal lobe (4/13).The signal intensity was isointense on T1-weighted MR images and hypointense on T2-weighted MR images.Enhanced MR images showed conspicuous enhancement of the dural edges.Corticosteroid therapy improved the clinical symptoms in 12 of 13 patients.Conclusions HCP typically causes headache and paralysis of multiple cranial nerves.Enhanced MRI shows characteristic manifestations.At present corticosteroid therapy is the treatment of choice followed by immunosuppressive agent and radiotherapy.

Objective To investigate the most sensitive methods for diagnosing spontaneous internal carotid artery dissection (sICAD) and spontaneous vertebral artery dissection (sVAD) respectively,for the sake of earlier and more accurate diagnosis.Methods Consecutive patients with sICAD and sVAD who visited the Department of Neurology and Radiology,Huashan Hospital Affiliated to Fudan University during 2008-2013 were retrospectively reviewed and the sensitivity of CT angiography (CTA),magnetic resonance T1-weighted fat-suppressed images (MR T1-FS) and digital subtraction angiography (DSA) for the diagnosis of sICAD and sVAD was compared.Results Eighty patients (62 male,18 female; mean age (45.7 ± 11.9) years) were included in the study.There were 99 arterial dissections in total,45 cases of sICAD,52 cases of sVAD and 2 cases of spontaneous middle cerebral artery dissections.The sensitivity of CTA,DSA and MR T1-FS for diagnosing sICAD was 97.5％ (39/40),90.0％ (36/40) and 69.6％ (16/23) respectively,while for sVAD was 89.8％ (44/49),84.6％ (44/52) and 100.0％ (27/27) respectively.Conclusions sICAD and sVAD have significant differences in many aspects including diagnostic strategies.CTA and MR T1-FS seem to be the most sensitive methods for the diagnosis of sICAD and sVAD respectively.Although DSA has been considered as the gold standard for the diagnosis of artery dissection,this imaging technique does not allow analysis of artery wall thickness,thus also has limitations.It is likely that the diagnostic sensitivity will be improved by combining CTA and MR T1-FS.

Objective To explore the clinical effect of mechanical perfusion for preserving kidney.Methods From May to October 2013, 36 donors’ kidneys were preserved by mechanical perfusion in the Department of Kidney in the 181st Hospital of Chinese People's Liberation Army.The donors’ kidneys were preserved , transported and perfused by the LKT-100 type Lifeport organ transporter and special software.General condition of patients and the relationship between resistance coefficient , flow velocity and occurrence of delayed graft function ( DGF) were analyzed.Results None of 36 recipients had graft loss.Thirty cases ’ (83%) renal function recovered well without DGF.Six cases developed DGF and returned to normal gradually after 3-18 days postoperative treatment.After mechanical renal perfusion for 1 h, 28 recipients with kidneys ’ resistance coefficient ≤0.3 mmHg/( ml · min ) hadn't developed DGF after transplantation.Among 8 recipients with kidneys ’ resistance coefficient >0.3 mmHg/( ml · min ) , 6 recipients developed DGF.Eight recipients with kidneys ’ flow velocity >100 ml/min hadn't developed DGF.Among 21 recipients with kidneys ’ flow velocity 60-100 ml/min, 1 case developed DGF.In 7 recipients with kidneys ’ flow velocity <60 ml/min, 5 cases developed DGF.Conclusions Mechanical perfusion for preserving kidney can improve graft quality and reduce the incidence of DGF in recipients.

Objective To observe the efficacy and safety of different doses of mizoribine to prevent rejection after renal transplantation. Methods Sorted by time of operation and odevity, 206 primary kidney transplant recipients were divided into 3 groups, including MMF group, MZR Ⅰ group and MZR Ⅱ group. All recipients in 3 groups were administrated CsA and Pred, combined with mycophenolate mofitile (MMF) in MMF group and mizoribine (MMF) in MZR Ⅰ and Ⅱ groups.The dosage of MMF was 1. 0 g/day, while dosage of MZR in MZR Ⅰ and Ⅱ groups was 100 and 200 mg/day, respectively. There was no difference in usage of cyclosporine (CsA) and prednisone (Pred) among 3 groups. 100, 60 and 30 recipients were followed up in MMF, MZR Ⅰ and MZR Ⅱ groups respectively in 5 years. During the follow-up period of 5 years, the incidence of acute rejection, patient/graft survival and adverse effects associated with drugs in three groups were observed. Results The patient/graft survival was 88. 3 % (53/60), 85 % (51/60) in MZR Ⅰ group, 90 % (27/30),86.7 % (26/30) in MZR Ⅱ group, and 88% (88/100), 86% (86/100) in MMF group, respectively (P>0. 05). There was no significant difference in incidence of acute rejection among MZR Ⅰ (10 %, 6/60), MZR Ⅱ (6. 7 %, 2/30) and MMF groups (9 %, 9/100). The incidence of severe pulmonary infection in MZR Ⅰ group was 3. 3 % (2/60), and 10 % (3/30) in MZR Ⅱ , and the former was lower than MMF group (15 %, 15/100) significantly. There was significant difference in mortality of severe pulmonary infection between MZR Ⅰ group (0, 0/2) and MMT group (73. 3 %, 11/15). The rate of ACR in MZR Ⅱ group (10 %, 3/30) was lower significantly than MMF group (30 %, 30/100) and MZR Ⅰ group (31.7 %, 19/60). There was significant difference in the incidence of hyperuricacidemia between two MZR groups (30 %, 56. 7 %) and MMF group (10 %)(P<0. 05), while the incidence of diarrhea and myelosuppression was lower significantly in MZR Ⅰ group than in MMF group. Conclusion MZR can prevent acute rejection after kidney transplantation effectively and safely. Immunosuppressive therapy including mizoribine is the best choice especially for high risk group because of susceptibility to infection and those who suffer from tenacious diarrhea owing to the side effect.
